The oil cylinder is locked between the transparent support seat and the front seat by the fixing shaft. The handle is pivotally combined to the front seat. The transparent support seat is locked to a distal end of the supporting seat. Part or whole of the transparent support seat is made of transparent material. The transparent support seat is made with a middle hole and an annular trench. A cup-like nut and an annular oil seal are locked to a distal end of the oil cylinder. The transparent support seat is sealed and locked to a bottom of the oil cylinder. By the transparent support seat, the user can check the amount of oil directly.

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention relates to components of manual pump oilcylinders, and particularly to a support seat of a manual oil cylinder,wherein a transparent support seat is combined to a bottom of the oilcylinder so that the amount of oil can be checked directly. An oilwasher is embedded into the transparent support seat and the bottom ofthe oil cylinder so as to have a preferred oil sealing effect.

[0003] (b) Description of the Prior Art

[0004] A prior art manual pump has a high pressure soft tube to connecta manual pump to the oil pressure tool so as to form a complex oilcylinder system for being used in various application, such as hydraulicpullers, hudraulic bender, hydraulic press, etc.

[0005] Referring to FIG. 9, the prior art manual pump is formed by anoil cylinder 10 and a handle 20, or moreover a pneumatic motor 30 forcontrolling the inlet and output of the hydraulic oil pressure with thepump 201. Other than being sealed by a plug 201, the manual oil cylinder10 has a steel support seat 40 locked to a bottom thereof so as to havea complete sealing. After being used for a longer time, the hydraulicoil in the oil cylinder 10 may be insufficient due to incompleterecycling. Thus the amount and dirtiness of the oil therein can not bemonitored.

SUMMARY OF THE INVENTION

[0006] Accordingly, the primary object of the present invention is toprovide a A support seat of a manual pump oil cylinder includes an oilcylinder, a handle and a transparent support seat. A distal end of theoil cylinder is locked by the transparent support seat. The oil cylinderis locked between the transparent support seat and the front seat by thefixing shaft.

[0007] Another object of the present invention is to provide a supportseat of a manual pump oil cylinder, wherein a handle is pivotallycombined to the front seat. The transparent support seat is locked to adistal end of the supporting seat. Part or whole of the transparentsupport seat is made of transparent material. The transparent supportseat is made with a middle hole and an annular trench. A cup-like nutand an annular oil seal are locked to a distal end of the oil cylinder.By the transparent support seat, the user can check the amount of oildirectly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Referring to FIGS. 1 to 4, the support seat of a manual pump oilcylinder of the present invention is illustrated. The support seat of amanual pump oil cylinder includes an oil cylinder 1, a handle 2 and atransparent support seat 3.

[0018] The oil cylinder 1, as shown in FIG. 1, has an oil injection holeat an outer wall thereof. The hole is sealed by a plug. A distal end ofthe oil cylinder 1 can be locked by the transparent support seat 3. Theoil cylinder 1 is locked between the transparent support seat 3 and thefront seat 13 by the fixing shaft 12 (referring to FIG. 8). The handle 2is pivotally combined to the front seat 13. The other structure isidentical to those in the prior art and thus the detail will not bedescribed herein.

[0019] The handle 2 is pivotally installed to the front seat 13 of theoil cylinder 1. One end thereof is installed with a pump 21 and iscombined to the front seat 13. In operating, the inlet and outlet of thehydraulic oil can be controlled.

[0020] Part or whole of the transparent support seat 3, see FIGS. 3 and7, is made of transparent material (such as plastics). The transparentsupport seat 3 is made with a middle hole 31 and an annular trench 32.The fixing shaft 12 passes through the middle hole 31. A cup-like nut 4and an annular oil seal 41 are locked to the distal end of the oilcylinder 1. The annular trench 32 is engaged to the oil cylinder 1 sothat a corresponding oil seal washer 5 can be embedded therein. Thetransparent support seat 3 can be sealed and locked to the bottom of theoil cylinder 1 (referring to FIG. 8), thereby, having a preferredsealing effect. In the transparent support seat 3, a plurality of ribs33 can be formed in the middle hole 31 for increasing the strength.

[0021] The transparent support seat 3 is locked to the bottom of the oilcylinder 1 for checking the amount of oil. When the oil is insufficientor dirt, it can be supplemented or updated at an optimum timing.Thereby, the manual pump oil is retained in a normal condition.

[0022] In above transparent support seat 3, an oil scale can beinstalled on the wall of the support seat (not shown) for checking thescale of the oil.

[0023] Above transparent support seat 3 has a stepped middle hole 31 forbeing penetrated and positioning the fixing shaft 12 and is locked tothe distal end of the oil cylinder 1 by a cup-like nut 4 and the annularoil seal 41.

[0024] The present invention is thus described, it will be obvious thatthe same may be varied in many ways. Such variations are not to beregarded as a departure from the spirit and scope of the presentinvention, and all such modifications as would be obvious to one skilledin the art are intended to be included within the scope of the followingclaims.
